    I am interested in selling TV boxes in South Africa.
    But we have certain apps that required that the Devices must meet the following:
    Devices that is not rooted or altered
    Supports Widevine DRM provided by Google
    Complies with google standard.

    This is required for Netflix, Showmax (South Africa Only), DSTV (South Africa Only) to run and install from the app store and to be able to do video playback.

    Can you guys help me with Firmware or devices that supports this?
    Waiting for your reply.

    We can skype talk as well if required.

    hope you can Help
